Our summer vacation scheme and trainee programme give you space to start your legal career with meaningful work from day one. 

Our summer vacation scheme is the route to a training contract at Marriott Harrison. We offer up to 18 places on our summer vacation scheme. 

As part of our summer vacation scheme week, you can choose which practice areas to explore and work on real cases. You will be immersed in Marriott Harrison’s culture and may also participate in activities such as an ‘Ask Me Anything’ with our managing partner, Daniel Jacob. 

We invite high performing summer vacation scheme participants to interview for our trainee programme and offer up to four training contracts to successful candidates. 

Our week long summer vacation scheme offers an immersive introduction to life at Marriott Harrison. You’ll take part in structured activities across our core practice areas, gaining hands-on experience and insight into the breadth of work we do. Expect meaningful conversations with people at all levels, interactive workshops, and real exposure to the kind of work you could be doing as a trainee. 

The experience is designed to give you a true flavour of our culture, supported by training and activities that give you the chance to connect with our people beyond the desk.

Your training contract will start the year after you complete your summer vacation scheme with us. Our summer vacation scheme experience is the foundation for your training contract at Marriott Harrison. Incoming trainees are invited to our social events so that by the time you join as a trainee, you’ll already have a feel for the firm, know the people you may be working with, and feel confident to transition into your first seat.

Supported by a structured 24-month programme of focused technical training, you will have the opportunity to rotate through our core practices, including venture capital and M&A, commercial, dispute resolution, employment and real estate. Small teams mean early client contact and responsibility on live matters. Each month, you’ll build knowledge in a new practice area while gaining hands-on exposure to matters that may cut across multiple specialisms. 

From the outset, you’ll be supported and trusted with real responsibility. Early tasks may involve drafting ancillary documents, but as you progress you’ll take on core documentation and could be engaging directly with senior lawyers on the other side, developing the skills and confidence to advise clients at the highest level and reach your full potential as a lawyer. 

Your development doesn’t stop at qualification. Through MH360 Academy, our dedicated training and development programme, we equip you with the technical expertise, commercial awareness and leadership skills to become a well-rounded, successful lawyer - and a key part of Marriott Harrison’s future. 

Our diversity of perspective keeps us distinctly ahead of the curve. We are united and empowered by a culture of deep collaboration and excellence, empathy and respect.

Our purpose is to equip future-focused companies, investors and individuals with the strategic foresight needed to make bold, informed decisions. We believe in our clients, in our people, and in long-lasting relationships and decisions that prioritise a sustainable future.

We currently pay SQE fees for successful applicants about to start their course. We do not pay for SQE or LPC in retrospect.
